Brown adipose tissue detection using positron emission tomography could help reduce urolithiasis risk

Area of Science:

• Metabolic Syndrome Research
• Urology
• Radiology

Background:

• Urolithiasis is often linked to metabolic syndrome.
• Brown adipose tissue (BAT) activation shows potential for improving metabolic syndrome.
• The relationship between BAT and urolithiasis in humans requires investigation.

Purpose of the Study:

• To investigate the association between brown adipose tissue (BAT) and the prevalence of urolithiasis in humans.
• To explore the correlation of BAT with calcification of the abdominal aorta (CAA) and metabolic factors.

Main Methods:

• A single-center retrospective cohort study analyzed 182 patient records.
• Positron emission tomography-computed tomography (PET-CT) was used to detect BAT.
• Logistic regression analysis evaluated associations between urolithiasis, BAT, and other clinical factors.

Main Results:

• Participants with detectable BAT had significantly lower rates of urolithiasis (10% vs. 37%) and CAA (50% vs. 79.6%).
• Higher body mass index was observed in participants with BAT.
• BAT presence and older age were independently associated with a decreased odds ratio for urolithiasis.

Conclusions:

• Increased brown adipose tissue (BAT) content is associated with a reduced risk of developing urolithiasis.
• The findings suggest a potential protective role of BAT against kidney stone formation.
• This research could inform novel preventive strategies for urolithiasis.
